I have been working on trying to learn how to properly setup a 'Visitor Account' on my laptop. Everything seem ok so far, I have a 
couple screenshots 'shown below' to ask what you may think about this scenario so far. 
Suggestions are certainly welcome.


		
		 <----------Terminal permissions


		
		 <----------Users shown in Cinnamon


		
		 <---------users, groups, etc.

Note: when 'visitor' is clicked 'not shown above' there is nothing but 'visitor' shown within 'Groups'.

Note: that I added 
visitor to administrator group 'that should be correct right in order to
 access visitor through admin? I can 'cd' into visitor as user 'paul. When I login to visitor from the splash screen and try to access 'paul' via terminal 'permission is denied'

The end goal is to ensure 'visitor' cannot access sudo or other sudoers or users files whatsoever'.

Any thoughts as far as how this may be setup improperly?

Thank you,
